Sunday’s playoff game between the Green Bay Packers and the San Francisco 49ers may be one of the coldest NFL games ever played. The Ice Bowl of 1967 currently holds that title with subzero temperatures that dipped to -13 degrees, the Journal-Sentinel reports.

Temperatures at Lambeau Field in Wisconsin are expected to reach negative two degrees at kickoff thanks to a record cold blast in the U.S. The original Ice Bowl was also played in Green Bay. The Packers defeated the Dallas Cowboys for the NFL Championship in that game. They’re hoping that cold temperatures will bring them similar luck against San Francisco.

Weather conditions have discouraged fans from snatching up playoff tickets. As of Friday morning, the game in Green Bay was not yet sold out. To encourage fans to attend, the Packers have announced they will offer fans free hand warmers, coffee and hot chocolate.
